Customs and Border Protection has begun the process of opening a new border crossing in a remote section of Texas that it says is the first Class B port of entry in the southwest since the agency was formed.

CBP published a Notice of Proposed Rulemaking in the Federal Register on Oct. 28 to create a new border crossing at Boquillas, TX, in Big Bend National Park. It said the proposed Class B port of entry will help facilitate travel and trade within the Big Bend-Rio Bravo Project area, filling a void in a long stretch of border between Presidio and Del Rio, TX where there is currently no port of entry. It added the crossing will also build on the already-robust border security in the area. The intended plan to re-open the crossing was announced in January by CBP Commissioner Alan Bersin.

The agency said the proposed Boquillas crossing will be a designated Class B port of entry — the first on the southwest border since the creation of CBP — which can be used by U.S. citizens, lawful permanent residents, Mexican border crossingcard holders, Canadians, and others exempt from certain documentary requirements with approved Western Hemisphere Travel Initiative-compliant documents.
